You might have answered you own question.
>> why haven’t more conservative pols been conspicuously supportive of Hayworth? <<
They may know about the infomercial and don’t like the tenor of that unfortunate affair.
Perhaps Duncan Hunter and Jim DeMint should have campaigned strongly for Hayworth then he would be sitting on a 64pc favorable, right?
Which begs the question, why haven’t more conservative pols been conspicuously supportive of Hayworth?
I’d say because McCain is owed a lot of favors and he’s calling them in this time, every single one.
He has fought tooth and nail spewing lies and distortions in ad after ad. He started running ads against Hayworth before Hayworth said he was running!
McLame wouldn’t attach Zero on real things like Bill Ayers, his radical friends, his lack of experience, etc. etc. but he’s fighting to the death for his Senate seat.
